Asus P5KC MB A1 Suite Software Problem

I recently upgraded my Intel Core 2 Quad box from Vista to Win 7 64. Now i have trouble with my motherboard software and utility programs like A1 Suite .. which i need for adjusting pc speed and fan settings etc..

I have contacted Asus support and this is what i got back.

---------------------------------------------------------------------------------------------------------------------------------------------- I have confirmed the probem with the relative department. The motherboard manufactured after 1/1/2007 maybe support Win7. Please use the driver from the chipset vendor first. Then keep paying attention to the website for any update about Win7. Sorry for all the inconvenience.

However i have tried to install what is available and they are not Official Win 7... but vista/XP ... the thing is.. the programs go to install then i get an error half way through stating Failed To Install ACPI Driver ...

If anybody has any idea how to fix this i would appreciate the help.

It's really is bugging me. I would like to turn down the internal fan speed.. as sometimes the sound gets a little annoying.
